R5.1 touches everyone. From e-resources to analytics, we’re all navigating the same questions: What changed? Will my dashboards still make sense? How do I keep trends comparable?
So we’re launching a three-part, community-first series to move from COUNTER R5 → R5.1 together—practically, calmly, and with plenty of real-world examples.

What you’ll get

• Clear explanations of what’s new in COUNTER 5.1 (straight from the source)
• Practical ways to keep data continuity and avoid broken KPIs
• Field notes from librarians and from CELUS on SUSHI, validation, and common pitfalls
• Live Q&A/discussion each time—bring your edge cases

Who should attend

Librarians, e-resources managers, consortia staff, vendors/intermediaries—anyone who touches usage stats or reports to stakeholders.

Why CELUS is hosting this

Because continuity matters. Comparable data makes librarians’ lives easier and decisions clearer. These sessions are community-oriented and tool-agnostic—use whatever system you like, and take away checklists and fixes you can apply anywhere.
